CORKSCREW.

SPECIFICATION forming part of Letters PatentNo. 401,672, dated April 16, 1889. Application filed September 3, 1888. Serial No. 284,441. (No model.)

T all whom, t may concern:

Be it known that We, SEYMOUR LANDON AL- vORD and EDWARD E. BROWN, of West Winsted, in the county of Litchfield and State of Connecticut, have invented a new Improvement in Corkscrews; and we do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full,

1o clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure l, a side view of the corkscrew as in the position for introducing the screw to the cork; Fig. 2, a side view of the same; Fig. 3, avertical central section, the parts in the position as with the cork extracted; Fig. at, a vertical central section through the handle, showing its attachment to the spindle; Fig. 5, a vertical central section illustrating the engagement of the handle with the sleeve and its escape from the spindle; Fig. 6, a niodiiication.

This invention relates to an improvement in that class of corkscrews which consist of a frame adapted to rest upon the neck of the bottle, with a corkscrew arranged therein so as to be forced into the cork, and in which a screw is adapted to be engaged with the corkscrew spindle after the corkscrew has been inserted, and whereby, under rotation of the handle, the said second screw serves as the means for drawing the cork, the obj ect of the invention being such. a construction and arrangement of the second screw, combined with. the spindle and handle of the corkscrew, that the continued rotation of the corkscrew spindle and handle in the same direction will iirst force the corkscrew into the cork, and 4o then withdraw the cork; and the invention consists in the construction as hereinafter described, and particularly recited in the claim.

A represents the base orsocket oi the frame B, which is adapted to rest upon the mouth of the bottle, as in the usual construction of this class of corkscrews. l

Concentrically over the socket the frame terminates in a neck, C, which is internally screw-threaded with a left-hand screw-thread. Into this left-hand screw-threaded neck a correspondingly lett-handthreaded. tube or sleeve, D, is placed, and so as to be free to be moved up and down, according to the rotation imparted to the sleeve. Through the tubular sleeve D the corkscrew-spindle E passes, and at its upper end is provided with a handle, F. For the attachment of the handle the spindle is reduced at its upper end to form a shoulder, e. The extension of the handle from the shoulder upward is constructed at its lower or 6o shoulde rend of angular shape, as at f. Above this angular portion the extension is still further reduced to cylindrical shape, as at g. Then at the extreme upper end a head, t', is made fast. The head is of larger diameter than 65 the diameter of the angular portion f.

The handle F is constructed with an opening through it, the lower portion of the opening corresponding to the angular shape of the extension f, and from that point upward the 7o opening in the handle corresponds to the diameter of the head, the head being cylindrical. This forms a chamber, Z, within the handle and below the head, into which a spring, m., is arranged. The upper end of the spring bears upon the head and the other end bears upon the lower end of the enlargement of the opening in the chamber of the handle, and so that the tendency of the spring is to force the handle down upon the shoulder c and into 8o engagement with the angular portion of the spindle, but yet permit the handle to be raised,l as indicated in broken lines, Fig. 4t, so as to take the handle from engagement with the angular portion of the spindle. Under this construction when the handle is engaged with the angular portion of the spindle the rotation of the handle will be imparted to the spindle and corkscrew; but when the handle' is raised, as indicated in broken lines, Fignt,geg` it is disengaged from the spindle and free to rotate without imparting rotation to the spindle.

The spindle E terminates at its lower end in a corkscrew, G, of usual shape. The length of the spindle between the handle and the screw is considerably greater than the length of the left-hand screw-sleeve, D, so that the spindle may have vertical or longitudinal free play, and so that it may be moved up and roo down through the sleeve--say as from the position. indicated in Fig. l to broken lines in 'top of the neck C. The frame is set upon the neck of the bottle, as seen in Fig. l, the handle, spindle, and corkscrew being drawn upward for this purpose. Then the handle is turned (it being understood that the corkscrew is a right-hand screw) to force the corkscrew into the cork in the usual manner for applying the corkscrew. The screw will enter the cork and the handle will correspondingly descend until the corkscrew is properly inserted. Then the clutching device between the handle and the sleeve engages the two. The

rotation of the handle is continued in thel same direction as for inserting the screw into the cork, and that rotation imparts a corresponding rotation to the sleeve D, and because of the left-hand screw-thread of the sleeve yD such rotation draws the sleeve from the frame, causing it io rise, as seen in broken lines, Fig. 5, and force the handle upward out of engagement with the angular portion of the spindle, thus leaving the handle and the left-hand screw-threaded sleeve free to continue their rotation. The handle takes a bearing against the head of the spindle. Consequently the continued rotation of the sleeve and handle will operate against the head of the spindle, so as to draw the cork from the bottle, as seen in Fig. 3, the rotation of the handle being in the same direction throughout the operation. Under this construction in extracting the cork it is only necessary to turn the handle in one direction, that turning being continued after engagement with the left-hand screw-threaded sleeve, D, until the cork is extracted. The engagement between the eX- tracting-sleeve D and the handle will be automatic and without any effort on the part of the person using it.

It will be understood that any suitable irregularity in the adjacent surfaces of the handle and sleeve, whereby automatic engagement will be made between the handle and sleeve, may be substituted for the notches on the one and projections on the other. For illustration, the surfaces may be serrated, as seen in Fig. 6, and it will also be understood that before using the corkscrew the left-hand screw-threaded sleeve, D, is to be screwed down into the neck to a suficient extent to permit a proper engagement of the corkscrew with the cork.

Ve do not claim, broadly, a corkscrew in which the handle portion is detachably engaged with the screw and in which the spindle is arranged through a screw-sleeve working in the frame, the thread of the said sleeve being the reverse of that of the corkscrew, as such, we are aware, is not new.

In a corkscrew, the combination of a frame, B, having a socket, A, at its lower end, adapted to rest upon the neck of the bottle, and having a neck, C, at its upper end, the said neck internally screw-threaded with a left-hand thread, a tubular sleeve, D, through said neck and correspondingly left hand screw-threaded, the spindle E, corresponding in diameter to the internal diameter of the sleeve D, but of a length greater than the length of said sleeve D, the lower end of the said spindle terminating in a right-handthreaded corkscrew, G, as an integral part thereof, a handle, F, upon the upper end of said spindle, the spindle extending through the handle, a portion, f, ofthe spindle within the handle made of angular shape, and acorresponding portion of the opening t-hrough the handle made of corresponding angular shape, the portion of the spindle above said angular shape f within the handle being of cylindrical shape, the upper end of the spindle constructed with a head, z', a spring, m, in the handle below and so as to yieldingly bear against the head t', and so that said handle may engage the angular portion of the spindle and impart its rotation thereto, or, disen gaged from such angular portion, may have a rotation of its own independent of the spindle, the upper end of the left-hand screwthreaded sleeve and the corresponding surface of the handle constructed of irregular shape, whereby contact between the handle and the said sleeve causes the said sleeve to partake of the rotation of the handle, all substantially as described.
